Answer 1

It is series type connection

Answer 2

Explanation:

Take a dry cell that has 1.5 volt EMF and a torch bulb, which can withstand a voltage of 3 volt with holder. Connect them, connecting wire is joined from one terminal of the cell, say positive to the other terminal of the bulb. The negative terminal of the cell is connected to another terminal of the cell. As soon as the connection is given, the bulb starts to glow. Compare the brightness of the light of this bulb with that of a torch light that is switched on.

On comparing the brightness of the bulb connected to the cell is lesser as compared to that of the bulb in the torch light. This is because the bulb in the torch light is connected to two cells that are connected and not a single one.

The bigger line on the dry cell indicates the positive terminal of the cell and the smaller one its negative terminal.

When two cells are connected in series, they are represented symbolically in a circuit diagram as shown.

The two cells in the torch are connected such that the positive terminal of the first cell is connected to one of the terminal of the bulb. The negative terminal of the first cell is connected to the positive terminal of the second cell. The negative terminal of the second cell is connected to the other terminal of the bulb through the connecting wire.

A group of cells connected in a regular order is termed “battery”. Thus the torch light consists of a battery containing two cells connected in a regular order..

Hope its help...
